Title: Anyone good with OpenGL?

Does anyone know how to use OpenGL? I really need help with textures specifically, but any insight would be appreciated.

Thanks,
Binder News

Try these tutorials: http://nehe.gamedev.net/ (http://nehe.gamedev.net/), texture mapping is in the 6th section. I was using them but I only got to #5 :P

Specifically, I am trying to load a png file as a texture. However, when I go to display it, it has a black background, not a transparent one.

/me starts hyperventilating

@Binder News, Idk what language you are using, but if it's a 2D texture SFML could be a good choice.
